DETACHAIBLE ROWBQAT-MOTOR.

I Application filed March 1,1915. Serial No. 11,414.

To all whom z't may concern: Be it known that I, CHRISTOPHER J.

MEYER, a citizen of the United States, re-

siding at Milwaukee, county of Milwaukee, and State of Wisconsin, have invented new and useful Improvements in Detachable Rowboat-Motors, of which the following is a specification.

My invention relates to improvements in that class of row boat motors, shown and described in Letters Patents of the United States, No. 1001260, dated August 22, 1911, and No. 1087162, dated October 12, 1912.

In the propelling mechanisms of the. class above referred to, it has heretofore been custom'ary to mount the pump upon the casing, which incloses the submerged gearing and provides bearings for the shaft which carries the propeller wheel, but the propeller wheels of this type are swung from side to side for steering purposes, and it is also desirable that they be reversible. In a companion application bearing even date herewith, I have shown and described reversing mechanism, in which the lateral thrust of the propeller blades is utilized to automatically reverse the propeller, means being provided for automatically relieving the propeller supporting shaft from tiller control, in order that the reversal may be thus automatically accomplished. But as each of these reversing movements takes place in the same direction of rotation about the axis of the supporting; shaft, it is not possible to locate the pump upon the casing of the propeller shaft, if a separate tube is employed to deliver the water from the pump to the water jacket of the internal combustionmotor.

The object of my invention therefore is to provide means whereby the pump may be supported in a stationary position in a propelling mechanism of this class and such a pump operated from the propeller shaft regardless of the rotative adjustment of the propeller and said shaft.

In the dr'awings Figure 1 is a side elevation of the lower portion of a propelling mechanism of the' row boat, as shown and described in said former patents. I Y

Fig. 3 is a detail view of a clamping member adapted to engage the supporting shaft of the propeller and to form a bearing for the segment block shown in Fig. 2.

Fig. 4 is a detail view of the pump and pump supporting clamping member detached.

Fig. 5 is a detail view showing the clampmember of Fi 3 in place. ike parts are i entified by the same reference characters throughout the several views. 1 is a tubular supporting shaft to the lower end of which a casing 2 is secured, which serves as a housing for the propeller shaft, the gearin connecting said shaft with a driving sha t extending downwardly through the tube 1, substantially as shown in the prior patents above. referred to. A pump actuating rod 3 is reciprocatedfrom the propeller shaft substantially as shown and described in said former patents, but for the purpose of my present invention, this rod 3 does not serve as a pump plunger but supports a ring 4, which loosely encircles the shaft 1 and forms an annular bearing for a pump plunger 5, which projects downwardly from the cylinder 6 of the pump carried by a clamping bracket 7 The upper end of the cylinder 6 is provided with anipple,8, havdesired position of adjustment by set screws 16, the arms being preferably provided with sockets 17 in which said screws may engage.

The segment block 14 is provided wlth a depending sleeve 18, which is engaged by the clamping bracket 7, which supports the pump. Said clamping bracket is provided with cars 20 through which the clamping bolt 21 may pass.

A clamping sleeve 25 embraces the propeller supporting shaft 1 above the'block 14. This sleeve 25 is split near its lower end and is provided with outwardly projecting ears 26, through which a clamping bolt 27 may pass, whereby the sleeve may be bound securely upon the shaft 1. The lower end of this sleeve aflords a bearing against which the segment block 14L abuts, and the upper end of the sleeve is provided with a catch 28 adapted to be engaged by a tiller lever, whereby the propeller supporting shaft 1 may be rotated to swing the propeller from side to side for steering purposes.

With the above described construction, it is obvious that the pump 6 will be supported and held in a stationary position by thebracket 11, arms 12, segment block 14, sleeve 18 and clamping member 7. Also that the propeller supporting shaft 1 will be supported from the block 14: through the clamping sleeve 25, which, however, is adapted to rotate upon the segment block 14, thereby permitting a rotary movement of the shaft 1. And in view of the fact that sleeve 25 is clamped to the shaft 1, it is obvious that it may be adjusted lineally to allow the shaft 1 to be raised or lowered, thereby adjusting the propeller in proper relation to the boat with which it is connected. The annulus 4, upon which the pump plunger 5 bears, will of course rotate whenever shaft 1 and easing 2 are rotated. But as this annulus is concentric with the shaft 1, it will bear upon the pump plunger 5 in any position of rotative adjustment. Therefore an upward movement of the reciprocating pump actuating rod 3 will be effective to operate the pump from any position of such rotative adjustment, and a downward movement of the rod 3 will permit a corresponding downward movement of the plunger 5, either by gravity or under the tension of a spring within the pump cylinder. By providing the pump cylinder with the clamping member 7 instead of permanently securing it to the sleeve 18, I secure the added advantage of being able to adjust the pump cylinder rotatively with reference to the sleeve 18 and thereby bring the pump outlet to the position most convenient for connection with a pipe leading to the water jacket of the motor.

I claim 1. A supporting member for propeller shafts, comprising a bracket engaging block having a downwardly projecting sleeve through which a propeller supporting shaft maypass, and a pump cylinder provided with a clamping member engaging said sleeve.

2. The combination with a propeller supporting shaft, of a sleeve loose on said shaft, a bearing sleeve clamped to said shaft above said loose sleeve, and a pump cylinder clamped to said loose sleeve.

3. The combination with a propeller supporting shaft, of a sleeve loose on said shaft, a bearing sleeve clamped tosaid shaft above said loose sleeve, and a pump cylinder clamped to said loose sleeve, together with a set of supporting arms connected with said loose sleeve and adapted to support the propeller shaft while permitting rotative adjustments thereof.

4. The combination with a supporting boat engaging bracket, of a sleeve connected therewith, a propeller supporting shaft extending loosely through said sleeve, a clamping member secured to said shaft above said sleeve and adapted to bear thereon to support theshaft from the sleeve and bracket, a pump cylinder secured to the sleeve, and a pump operating rod supported from the propeller supporting shaft and provided with a ring encircling said shaft, said pump cylinder having a plunger arranged with one end bearing upon said ring, substantially as described.

5. The combination with a stationary propeller supporting member, of a pumpcylinder adjustably clamped thereto, a propeller supporting shaft extending through said stationary support and rotatively adjustable therein, and means carried by the propeller supporting shaft for operating the pump in any desired position of rotative adjustment. In testimony whereof I affix my slgnature 1n the presence of two witnesses.
